Israeli-Arab protesters hold a poster depicting Egypt's President Hosni Mubarak (r.), a Palestinian flag (c.) and a sign, which reads 'Honor and freedom are demanded for all Egyptians,' during a demonstration outside the Egyptian embassy in Tel Aviv, to show support for the people of Egypt on Feb. 1.

Part of that quiet is due to a rare common effort from the Palestinian Authority (PA) in the West Bank and Hamas in the Gaza Strip to suppress vocal support for Egyptian protesters. Both sides dispersed solidarity demonstrations that were planned for last Sunday and Monday.

The PA and Hamas both maintain close ties with the Egyptian government. Mr. Mubarak has been a key supporter in Israeli-Palestinian peace talks that have involved the PA. Although Egypt has helped maintain the blockade on the Gaza Strip, Mubarak also turned a blind eye to the brisk tunnel trade under the Gazan-Egyptian border, and has allowed aid into the strip. Further, Mubarak has attempted to mend the rift between the Gaza-based Hamas and Fatah, which rules the West Bank.
